I have a pretty good idea of what gear I need to get to become a more effective tank but I would like to hear some suggestions incase I'm wrong. I've tanked Maiden and Prince without any problems at all. I've OT for ZA and Gruul's (lynx gives me troubles his lash can drop me).
What gear should I work towards getting first?
Any advice would be helpful.
Slikk's is awesome and you'll use it for a long time, but Devilshark is a great blue. While you'll be getting Slikk's eventually, I would definitely go Girdle of the Fearless with no regrets.
For boots, nothing much is great early on. Flesh Beast's Metal Greaves (quest reward) is a decent stopgap until you see Battlescar/Boots of Elusion. I personally just got the PvP boots and used them for awhile.
Mino's suggestions are money, you are moving in the right direction but you have alot of holes you can fill up pretty easily.
You mentioned boots. Go back to ZA and beat some [item]Jungle Stompers[/item] out of the bear boss. If you can't get those, I see you're a BS...finish that out and get the pattern for [item]Red Havoc Boots[/item] though the Stompers are better and should be easier to get.
You have a glut of Defense and not that Def is bad but you could stand to ratchet up your EH a bunch. The [item]Ring of the Stalwart Protector[/item] is pretty hawt and while remaining well above critical, it trades def for raw avoidance and a ton of stamina. Slik's is nice but Devilshark is pretty stout for a blue item and the BV gives you some threat.
A Darkmoon: Vengeance card would be nice to have in that 2nd trinket slot opposite the Commendation.
As stated, the Belt is probably going to be your best bet for a badge upgrade because it adresses so many issues at once, ie, armor, stam, threat and even provides more def rating.
